如何从ajax上的客户端脚本调用WCF服务 [英] How to call a WCF service from client script on ajax
问题描述
我的服务合约名为IService1，如下所示
My service contract, named IService1, is as follows
using System.ServiceModel;
using System.ServiceModel.Web;
namespace WcfServiceDemo
{
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
string GetData(int Value);
}
}
这是我的服务实现，
Here's my service implementation,
using System.ServiceModel.Activation;
namespace WcfServiceDemo
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
public string GetData(int Value)
{
return string.Format("You entered: {0}", Value);
}
}
}
我的web.config，
My web.config,
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name ="ServiceBehavior">
<!-- To avoid disclosing metadata information, set the value below to false before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="EndPointBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<services>
<service name ="WcfDemoService" behaviorConfiguration="ServiceBehavior">
<endpoint address="" binding="webHttpBinding" contract="IService1" behaviorConfiguration="EndPointBehavior" />
</service>
</services>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--
To browse web app root directory during debugging, set the value below to true.
Set to false before deployment to avoid disclosing web app folder information.
-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
使用WCF服务的脚本，
Script for consuming WCF service,
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
Enter a number:<input type="text" id="txtNum"/>
<input type="button" onclick="AlertEnteredNum();"/>
</div>
</form>
<script type="text/javascript" src="Script/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
function AlertEnteredNum() {
var Value = $('#txtNum').val();
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: 'Service1.svc/GetData',
data: '{"Value": "' + Value + '"}',
dataType: "json",
processData: false,
success: function (data) {
alert("Success: " + data.d);
},
error: function (result) {
alert("error: " + result);
}
});
}
</script>
</body>
</html>
始终错误回调
Always error callback
error: function (result) {
alert("error: " + result);
}
被执行
我想我需要在IIS上托管，因为我是在我的配置中设置兼容模式。
但是，当我在IIS上托管这个服务时，我得到的解析器错误为targetFramework属性的值无效：'4'。错误：FrameworkName不能少于两个组件或多于三个组件。
参数名称：frameworkName。
任何建议......
gets executed
I think I need to host on IIS, as I am setting compatibility mode in my config.
But, When I host this service on IIS, I am getting parser error as " The value for the targetFramework attribute is invalid: '4'. Error: FrameworkName cannot have less than two components or more than three components.
Parameter name: frameworkName."
Any suggestion...
推荐答案
（' ＃txtNum'）。val（ ）;
('#txtNum').val();
.ajax（{
type： POST ，
contentType： application / json; charset = utf-8 ，
url：' Service1.svc / GetData'，
data：< span class =code-string>' {Value：' + Value + ' }'，
dataType： json，
processData： false ，
成功：函数（数据） {
alert（ 成功： + data.d）;
}，
错误：函数（结果）{
alert（ 错误： +结果）;
}
}）;
}

最后得到了我的错误&这是解决方案。
只需将配置中的服务元素更改为：
Finally got my mistake & it's solution.
Just needed to change the service element in config as:
<services>
<service name="WcfServiceDemo.Service1" behaviorconfiguration="ServiceBehavior">
<endpoint address="" binding="webHttpBinding" contract="WcfServiceDemo.IService1" behaviorconfiguration="EndPointBehavior" />
</service>
</services>
其中name =WcfServiceDemo.Service1的格式为namespace.ServiceImplementationName& contract =WcfServiceDemo.IService1的格式为namespace.ServiceContractName
where name ="WcfServiceDemo.Service1" is in format "namespace.ServiceImplementationName" & contract="WcfServiceDemo.IService1" is in format "namespace.ServiceContractName"
